Pipe identification game

[Djg8493]

   I have come across two separate sets of pipes that are believed to be for AC rd350s but I am not sure.  I checked the identification posts but could not identify, the main thing I am questioning is both sets have one pipe that is angled at the end?  If not for that I would guess early Sepc 2 but I am sure someone on here has more experience.  While there are some differences both sets to look very similar to me...  Can anyone help verify what they fit and make??  Thanks

the mounts look like torque engineering pipes as do the welds. are they very heavy? silencer looks very different though. maybe a modded set.  thats a good one.
